Which sentence contains a misplaced modifier
(1) Tony planned to mow lawns and do light landscaping as a summer job. (2) However, he needed to invest some money in his future business.
(3) He bought his truck from a friend that was only two years old.
(4) He borrowed the money from his father, who made him sign an official promissory note.
Answer: (3) He bought his truck from a friend that was only two years old.
Explanation:
The placement of a modifier can create confusion about the meaning of a sentence. In this example, the modifier is "that was only two years old." However, since it´s positioned after "a friend," it becomes uncertain whether is the friend or the truck that was two years old. To fix this kind of mistake, we have to move the modifier closer to the noun it modifies:
He bought his truck that was only two years old from a friend.
